ESPECIPICATION forr ing part Letters Patent No. 383,758, dated May 29,1888.

Application filed January 5, 1835. Serial No. $259,822.

To (LZZ whom it may concern:

Be it known that l, \ViLnnLM FRIEDRICH NEDLnn, asubject of the Emperorof Germany, and a resident of Hamburg, in theGorman Eur pire, haveinvented certain new and useful Improvements in Fare-indicatingApparatus for Cabs and other Vehicles, of which the following isaspecification.

My invention (for which I have obtained Letters Fat-cut in Belgium, No.76,ri37, dated February 21, 1887) relates to improvements in apparatusfor automatically indicating the fare due on a cab or other publicconveyance, according to time or distance; and the objects of theseimprovements consist, first, in the provision of a fare-indicator with adial-plate upon which the fare to be paid for each hiring is indicated,in order that when the hand of the indicator has passed around the wholeor part of the circumference of the dial a number corresponding to thedistance passed through presents itself opposite an opening, and servesfor the calculation of the fare independently of the motion of theindicatinghand; and, second, of means for indicating upon the dial theminimum fare which must be paid for hire, no matter whether thecorresponding distance or duration of time has been attained or not. Iattain these objects by the mechanism illustrated in the accompanyingdrawings, in which Figure l is a front view of the apparatus, the handand the dial-plate removed. Fig. 1 is a front view of the apparatus,showing the hand and dial-plate and the w reels indicating the totalamount received by the cabman. Fig. 2 is a cross-section of theapparatus on the line 2 2, Fig. 1. Fig. 3 is a front view of the samewith some parts omitted. Figs. 4: and 5 are side and front views,respectively, of the cam and its notched disk. Figs. 6 and 7 are frontand side views,res1: ectively, of the indicating star-wheel. Fig. 8 is afront View, similar to Fig. l,with parts removed. 9 is a plan viewthereof, with parts in section; and 10 to 13, inclusive are detail viewsshowing steps in the operation of the auxiliary mechanism.

Similarletters refer to similar parts throughout the several views.

According to the first part of the said invention, the main shaft (1,Fig. 2, of the ap- Xo model.)

Patent d in Belgium February 21, 1e87, No. 713,437.

paratus is operated by clockwork, for charging by time, or from a wheelof the vehicle, for charging by distance, neither of which means isshown, i s the same form no part of my invention. A ratchetwheel, l), isfined upon the shaft c, and causes the lever d,wh1ch engages therewithby means of a projection, d, (see Fig. 1,) to oscillate upon its pivot.Through the medium ofa pawl, c, suspended from the lover (1, tworatchet-wheels, of, (see Fig. 2,) of equal diameter and having an equalnumber of teeth, are rotated. The rear ratchctwheel, c, is rigidlyconnected with the shaft 6, which carries the hand 0, and is sup portedin a back plate, h. The front ratchetwheel, f, moves loosely upon asleeve project ing from the plate h. The ratchet'whcel f is connectedwith a toothed whcehf, which operates the wheels f f of the dialmechanism. (See Fig. 1.)

The wheels f f" of the dial mechanism are designed to iutermesh, and aresecured adjacent each other, back of an opening in the dial, as shown,and are provided on their faces with suitable numerals for calculation.1 third wheel, f is generally used in connection with the wheels f 2 f.

Upon the front part of the liand shaft e, which is square, is placed acam, 0, Figs. 3, 4-, and 5, the projection 6" of which engages with thepinion g of the star-wheel g, Figs. 1, 3, 6, and 7. On the surface ofthe star-wheelg are placed numbers which serve for indicating the amountof fare, (in the apparatus illustrated in the accompanying drawings thefigures 0, 5, 10, 15, 20, and 25.) The cam projection 0 having engaged apin of the pinion g, 3, turns the latter forward a distance equal to onetooth during the next displacement of the hand.Aspringpawhg,materiallyassiststhe rapid movement of the star-wheel bymeans of the special shape of its nose, which will bring the pinion g"into the right position and fix it there as soon as the respective pinof the pinion g has passed the nose of the pawl g". The ratchet-wheel chas, however, also for its object to return the dial mechanism to thezero position, after the hiring is ascertained, without affecting theoperating mechanism. For this purpose the ratchctwheel c is arranged asa springbox, which during its movement coils a spring, 9, insertedtherein. The said spring is fixed at its outer end to the interior wallof the spring-box, (see Fig. 8,) and at the other end to the stationaryplate 71, serving as a bearing for the hand-shaft e A verticallydisposedbolt, (P, is passed up through the circular inclosing-casing, and isencompassed by a spring, at, which normally holds it in a loweredposition. This bolt d is passed through an aperture in the thickenedportion of a flat plate, d, to which is pivotally secured the lower endof a spring-held pawl, c, engaging the ratchet-wheel e. \Vhen thedisengagingbolt d is pushed in in opposition to the spring (1 thepawl-lever d is raised, the bolt d pushing against a projection, d, ofsaid lever d. The operating-pawl c, as well as the stop-pawl c, is thusmoved out of engagement with the main ratchet-wheel e. The action of thespring therein then turns the said wheel and, by the engagement of theprojection e of the cam 6 which is fixed to the wheel 6, with thestarwheel pinion g, the star-wheel 9, so far that the arm g on thepinion g strikes against a projecting pin, 6, on the cam-disk e, andthereby stops the ratchet-wheels.

The ratchet-wheel b is engaged by one end of a spring-held pawl, pivotedat its lower end to one end of a lever, 9 which is engaged by a stud orpin, of the plate d, as shown in Fig. 8. By this means the ratchet-wheelb is held as against a reverse movement.

In order that during every full rotation of the cam c the star-wheel 9shall turn only a distance equal to one tooth, a notched disk,e is fixedupon the cam 6 The notch in the disk 6' is exactly long enough for atooth of the star-wheel g to pass through when the disk 6 turns with thecam e*. The notch then changes its position, so that the next toothstrikes against the periphery of the disk e. The division of the pinion9 should be such as to admit of a maximum in duration ofthe hiring or ofa maximum length of the drive, respectively, which maximum cannot bereached under ordinary circumstances, The arm g on the star-wheel piniong is stopped by a pin, 9", Fig. l. i

It will .be understood that the hand 6 is operated by the turning of theshaft 6, the pinion of which is engagedby the pawl c, operated by theleverd and ratchet-wheel b. However, in order to obviate inconveniences,a minimum fare is usually fixed for public vehicles, which fares have tobe paid in every case. The lever d is therefore provided with amechanism which allows it as soon as the vehicle is occupied by apassenger to at once turn the shaft carrying the hand so far thatthe-latter indicates the minimum fare, but then the bolt d bears,in araised position. When a passenger enters the vehicle,the bolt cl will bereleased and descends by reason of the action of the spring (1.

The release of the bolt d can be effected by the hand of the driver, orautomatically by suitable means. (Not shown.)

The lever d,aeted upon by the spring difollows the bolt, and its pawlcengages with the ratchet-wheel e, and accordingly moves the shaft 6,carrying the hand e",round the dial to indicate the minimum fare. At thesame time the projection d of the pawl-lever d has penetrated betweenthe teeth of the main ratchetwheel I), and is then gradually lifted bythe displacement of the latter in correspondence with the distancepassed over or with the time. Besides the pawl-lever (I, there is anauxiliary lever, 00, ofexactlysimilar shape, only shorter, that does notreach to the disengaging-bolt (P. The projection 00 of this auxiliarylever :0, which is pressed down by a spring, a engages with the mainratchet wheel I), and consequently the auxiliary lever a: makes at firstthe same motion as the pawl-lever d.

On the auxiliary lever as, however,is arranged a disk, 00 which tends toturn the spring 4v, acting upon the pin .70 The spring or bears againstthe pin :0 of the disk w normally holding the latter in the positionshown in Fig. 8. A pin, a, fixed in the lever 03, limits the angularmovement of the disk 00 in one side of which is formed anotch or groove,against the ends ofwhich the pin 00 is designed to comein contacttolimitthe movement of the disk, (see Figs. 8, 11, 12, and 13,) which arearranged upon the periphery of the disk :0 almost diametrically oppositethe notch or groove for the stop-pin w, and with these teeth a pawl, 70,(see Figs. 8,10, 11, 12, and 13,) pivoted upon the auxiliary lever 00,and the arm at of an angle-lever, m it, upon the casing of the apparatusengage. As the fulcrum of the angle-lever m n is fixed, the disk :0 whenthe auxiliary lever 00 rises,is turned a little in opposition to thetendency of the spring or, so that the pawl k can engage with the nexttooth above in the disk. On the descent of the auxiliary lever 40, thelever-arm m engages with the next tooth, and thus the disk or" isgradually turned within the limits of the notch for the stop-pin 00,Figs. 8, 10, 11, 12, and 13. In the motion of the disk as, however, acam-sector, l, rigidly connected therewith, participates, the lattercontrolling the position of another angle-lever, op, pivoted in thecasing.

The arm 19 of the angle-lever 0 p is acted upon by the spring 1) andbears against the periphery of the cam-sector Z. The lower projectingpart of the latter enters first into ac tion and keeps the lever 0 p insuch a position that a hook, 0, on the arm 0 cannot engage with the pini on the pawl-lever d, Fig. 8; but as soon as the projection 50 passes atooth of the main ratchet-wheel b the disk :17 is turned a distanceequal to one tooth in a direction opposite to the direction of thearrow, Fig. 8,

IIC

and the arm 1 now passes into the recess of the cam-sector Z, which hasbeen turned likewise a little downward. The projection 0 then passesbelow the pin iof the pawl-lever d, and thus stops the latter in theraised position, Fig. 10. This stoppage lasts as long as the arm p restsin the notch of the cam-sector Z, Figs. 10, 11, and 12'. If the latteris, however, turned round so far that its upper projection presses backthe arm p, the projection o releases the pawl-lever d, Fig. 13, whichnow swings up and down with the auxiliary lever a and consequently bymeans of its pawl 0 turns the lfltClli--Wlll$ c and f, and with theformer also the shaft c, carrying the hand. When, consequently, thelever dis raised by the disengagingbolt (2*, the projection in (seeFigs. 8, 10, and 13) of the lever-arm m pushes back the pawl 7;,inasmuch as the angle-lever m n is turned alittle by the ascending pin2', that bears against the arm n. Ihe spring as" then pushes back thecamdisk a into its original position, Fig. 8.

Having now particularly described and as certained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. The combination, inafare-indicating apparatus 'l'orcabs and other vehicles, of the dial-plate, the ratchetwheel Z), the twopawllevers (Z and the disk 0;", the sector Z, the indicating-hand, andthe angle-levers m a and 0 p, for the purpose of stopping automaticallythe movement of said hand after its first leap over a certain part ofthe divisions on the dial plate to a point indicating the minimum lare,substantially as set forth.

2. In a fare-indicator for cabs or other vehicles, the two pawl-levers dand w, the disk m the sector Z, the indicating-hand, the anglelevers m nand 0 p, and the ratchet-wheels, in combination with the ratchet-wheel6, its spring, the spring-held disengaging-bolt having contact with saidpawl-lever d, and the pawls c c, substantially as shown and described,whereby a disengagement is effected after a certain distance or timeequivalent to the minimum fare has been exceeded, as set forth.

3. In a fareindieating apparatus, the com bination, with theratchet-wheels, the main shafts, and the pawllevers d w, or" the disk ehaving the projection e, the notched disk' e the star-wheel g, and thepinion 9, having the pins, substantially as shown and described.

4. In a fare-indicating apparatus, the combination, with theratchet-wheel b and the pawl-lever d, of the auxiliary pawl-lever w, thedisk 00 having a notched and toothed edge, the sector Z, having thegroove, the pawl L, the anglelevers m a and 0 the latter engaging astop-pin, t, of the lever (Z, and the spring is, engaging a pin, w",substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this ..3d day of April, 1887.
